3.2. General safety instructions
The following basic instructions must be observed in all cases:
• The device must not be placed in service until the manual has been read and under-
stood
• The power device for generating the power supply voltage must be reliably insulated
electrically by means of double insulation and a safety transformer according to DIN
VDE 0551 (corresponds to IEC 742).
• The device must not be used outside the specification without suitable protective mea-
sures
• No unauthorized tampering with the device is permitted
• Do not point the device directly at the sun or measure into the sun
• Do not remove the warning instructions or rating plates
The radiation emitted by a Class 1 laser is harmless. This type of laser instrument can
be operated by anyone.
The system operator is responsible for planning, assembly, commissioning, operation,
and maintenance of the system.
Installation and commissioning of all devices must only be performed by personnel spe-
cially trained for that purpose.
Danger!
This symbol identifies an immediate and present danger.
Failure to observe this warning may result in personal injury or even
death.
Warning!
This symbol warns of a possible malfunction or hazard.
Failure to observe this warning may result in personal injury or exten-
sive damage to property.
Caution!
This symbol warns of a possible malfunction.
If the instruction given in this warning is not heeded, the device and any
plant or systems connected to it could develop a fault or even fail com-
pletely.

The protection of the system and operating personnel is not ensured if the module is not
used according to its intended purpose.
Observe the applicable laws and regulations for use and for the intended purpose. The
devices are only approved for proper use in accordance with intended purpose. Any oth-
er use voids all warrantee claims and manufacturer's responsibility.
Use only recommended original accessories.
If you are unable to eliminate malfunctions, take the device out of operation. Secure the
device against accidental operation. Return the device to Pepperl+Fuchs for repair. Own
interventions and modifications are potentially hazardous, and any guarantee and man-
ufacturer's liability shall become void.
Dispose of the useless device in keeping with the applicable national legal regulations.
For example, you can take the sensor to the designated collection point for electronic
scrap.
The LS600 corresponds to the laser protection class 1 and is eye-safe
according to DIN EN 60825-1.
In applications with shelf distances and moving carriages, care must
always be taken to observe the applicable safety regulations. Failure to
do so will result in grave danger to life and limb!

4 Identification
• Optical data transmission for InterBus-S.
• Range: 0.5 m ... 200 m; /RT: 0.5 m ... 100m
• Galvanically isolated interface
• Baud Rate: 500 kBaud
• Indication of status and functionreserve by LED´s
• Large-scaled alignment aid, red flashing
• Integrated telescopic sight
• Input for switching off the transmitter
• Power supply: 24 V DC ±25%
• Function reserve outputs, P-switching
The LS 600-DA-IBS is a two-part light beam system for the serial infrared data transmis-
sion over a range of 200 m with a baud rate of up to 500 kbaud.
The devices contain each one transmitter andreceiver sothat to built one full duplexpath
just one pair of devices is required. The transmission takes place in real time and is pro-
tocol free. The bus driver termination is due to InterBus-S.
4.1 Data transmission
The data are transmitted in full duplex mode. They are carried by infrared light beams.
The light is modulated by frequency shift keying (FSK).
To avoid interference, for both directions of transmission are chosen two different center-
frequenciesF1andF2,i.e.thetransmitter in the unit LS 600-DA/ F1 works with frequency
F1, the receiver in the same housing works with F2, and vice versa on the opposite side.
The red function indicator LED under the covering of the viewfinder on top of the housing
illuminates, when the signal strength is just sufficient for operation. (function reserve fac-
tor 1). The data transmission is only released after having passed this signal level.
When signal strength reaches the double value of that level, the green function indicator
LED illuminates and shows a sufficient function reserve. The indication of function re-
serve is independent from data transmission.
An additional optical system was integrated besides the receiver-lens to ease the align-
ment. It flashes red, after switching power on. This grants the receiver to be perceptible
even on a long distance.
After adjusting the devices on at least signal level of factor two, this indication goes out.
4.2 Interface
The LS 600-DA-IBS has a data refreshing circuitry as well as data flow circuits being gal-
vanically isolated from the power supply.
For indicating bus-activity there is a yellow LED for receiving data, a green one for trans-
mitting data.
In case of light beam interruption, the idle-state level "low" is automatically activated due
to falling below the level of function reserve factor 1.
It is very likely that data messages are destroyed in the moment of turning to complete
interruption. This can only be avoided if the interruption is avised with a maintenance sig-
nal, which is usually used for switching off the transmitter.
The InterBus-signal RBST (BCI) is not served.

5 Mounting/Alignment
The units are fixed into position by means of the mounting-bracket.
On the upper side of the housing is a viewfinder for the telescopic sight which can be
used for approximate alignment. The receivers lens of the opposite unit should be sigh-
ted so that it lies next to the marked center.
The housings, as opposed to the mounting bracket, are adjustable vertically and horizon-
tally.
The horizontal adjustment angle is ±4°,
the vertical adjustment angle is ±90°.
The alignement should be done preferably at the maximum distance but at least in a dis-
tance of 7 to 10 meters. The device has to be adjusted until the red flashing light of the
opposite side become extinct. After doing the same procedure on the opposite side the
alignement is completed. The alignement must not be changed at low distances.
Note that within the short range the optical receiver is overdrived so a correct adjustment
based on signal strength display is not possible.
If the minimum distance is as short as 2 meters the optical connection between the de-
vices must be accomplished by special kind of mounting:
1. The view of sight can be expanded up to less than 1m by performing a parallel shift of
the optical axis of app. 40 mm. The telescope pointer is to aligne to the middle of the
appropriate transmitter lens.
2. The head-first mounting of one device provides a short distance range of less than
500 mm. Good results of adjustment are obtainable if the top of telescope pointer ma-
king coincide the middle of the receiver optics. Helpfully in this case is to power off the
devices to prevent glaring by the red flashing light.
The desired orientation (90°, 180°, -90°) can be accomplished by unfixing the four allen
screws at the bottom plate and relocating the flange to the appropriate side of housing.
